When I feel this way, walking up stairs gives me a forceful heartbeat, shortness of breath, and near
syncope. I dont care what anyone says, but anxiety does not cause exertional near
syncope,
and I will never believe that.. But, my Thalliuam stress test, cardiac CTA, Echocardiogram, CBC, CMP, Liver, Thyroid, BNP all check out normal. Actually, the Thallium test showed anterior/LAD hypokinesis but CTA was normal.
